Shimano Dura-ace DI2 RD-R9150 Rear Derailleur 11-SPEED

With the Dura-Ace Di2 RD-R9150 rear derailleur, Shimano introduces Shadow-profile technology known throughout the MTB sector. Thanks to its extremely flat construction and more direct positioning, damage is unlikely and cleaner shifting operation possible, even on uneven surfaces. As usual with Di2, this is done seamlessly with very little effort. The rear derailleur also features Synchro Shift functionality, allowing the front derailleur to adjust automatically, and here is further complemented by Semi-Synchro Shift. This means the rear derailleur is shifted accordingly when the front derailleur is engaged. The RD-R9150 consists almost entirely of super-light carbon and with its short cage length (SS type) for 11-speed cassettes up to 11-30.
